Integrated security manufacturer TDSi has unveiled the latest version of its powerful but highly flexible and secure access control GARDiS software ? Version 2.4. New enhancements include an enhanced Site Plan function, integration to Microsoft Active Directory, and Distributed Communications support for full security and business systems network integration. GARDiS v2.4 includes an enhanced Site Plan function which enables a secure access control system to be planned/built based upon locational benefits, rather than just from an equipment list. Icons representing the various components can be moved onto the site plan to design and optimise the best solution for the needs of the organisation and its teams.
